I would imagine that this makes sense for a large subset of deliveries, if 30-50% of deliveries can be done with drones, not only will it still be worth it, but I imagine those customers will likely buy more from the store, especially if they can make it same-day delivery

I'm not so sure drone-to-drone anti-collision detection is a solved science. Maybe it is as simple has 802.11p or v2x announcements to determine hight and traveling plane.
